Louise Lu thought she was caught up in a terrorist attack when a pickup truck crashed into a Richmond Hill hair salon Friday morning.

“We heard this massive shatter of glass and said what is this,” she recalled in the aftermath. “We thought the tempered glass had shattered and collapsed.”

Lu has been a customer for the past seven years at the NRG Salon and Spa in Hillcrest Mall, located near Yonge St. and 16th Ave.

“More glass started flying, the walls started going...we thought it was a bomb...,” she said, describing the frightening incident.

Once the dust settled, she saw a white Dodge Ram pickup truck in the salon.

“Then we thought, ok terrorist attack, and this is it,” said Lu. “So we were waiting any moment for guys to come up with weapons.”

She and others frantically searched for anyone who might be injured inside the salon before looking for the quickest escape route.

Lu had an appointment to have her hair coiffed for a weekend wedding and would have been sitting where the truck burst into the salon had she not been running behind.

“For once I am grateful that I was late for my appointment,” said Lu, before getting into her Maserati, with her sister at the helm.

In fact it was not a terrorist attack but rather a different attack that caused the mayhem around 10:20 a.m.

“What we know is the adult male driver of the pickup truck suffered from a medical emergency and ended up losing control of the vehicle and collided with the store,“ York Regional Police Const. Laura Nicolle said.

“There were four people inside the (salon) but fortunately nobody was seriously injured,” she said, adding their injuries were all minor in nature.

By 1:30 p.m. the pickup was removed from the building and work crews were boarding up the gaping hole at the front of the salon.
